Resumen
The processing of materials by cutting with abrasive tool is carried out by means of thousands of grains bonded together as a single whole. The quality of abrasive tool is defined by cutting properties of abrasive grains and depends on features of spreading of temperature field in time and in abrasive grain volume. Grains are exposed to heating and cooling during work. It leads to undesired effects such as decrease of durability of grain retention in the binder, hardness, intensification of diffusion and oxidation processes between the binder and grain, the occurrence of considerable temperatu

Resumen
Thousand-grain weight is a key indicator of crop yield and an important parameter for evaluating cultivation measures. Existing methods based on image analysis are convenient but lack a counting algorithm that is suitable for multiple types of grains. This research develops an application program based on an Android device to quickly calculate the number of grains. We explore the short axis measurement method of the grains with morphological thought, and determine the relationship between the general corrosion threshold and the short axis.

Resumen
The microstructures and mechanical properties of cold upsetting magnesium alloys were investigated upon anneal under different conditions. The results show that a large amount of twins were observed in the original grains of cold upsetting AZ31 magnesium alloys. The twins disappeared gradually and recrystal grains formed after anneal. The volume fraction of the recrystal grains increases as the strain of samples rises. Recrystal grain size grows large with the elevated annealing temperature. Recrystal grain size reduces at first and then grows as the annealing time is prolonged. In addition, c

Resumen
Favorable weather and climate conditions for growing grain are also favorable for the livelihoods and reproduction of pests of grain stocks, and especially for wheat bug (Eurygaster integriceps Put.). Grain damaged by this pest loses its genetically incorporated properties, negative changes occur in the quantity and quality of gluten. Due to the ingestion of bug’s saliva with its special enzymes into the grain, the baking properties of the flour from such grain deteriorate – the dough becomes liquid, sticky, it loses elasticity. Thus, the issue of further effective use of grain damaged by the

Efficiency of the polishing process is determined by the properties of abrasive grains, including its form parameter and orientation in the body of the grinding tool. It is possible to improve the operational characterizations of the grinding instruments, in particular – cutting discs, by ordering of the grain geometry, selection of the rational form and orientation of abrasive grains for specific processing conditions and parameters of the power load.

Resumen
AbstractClimate change has become one of the most profound threats to smallholder agriculture in semi-arid and arid areas. Farmers in this sector are especially vulnerable to climate change due to reliance on rain-fed agriculture, limited access to capital and technology among other challenges. While several potential adaptation options exist, many barriers hinder effective adoption of these practices, hence production in marginal areas remains very low. This chapter discusses crop adaptation through the adoption of small grains in Zvishavane rural, a semi-arid area in Zimbabwe. Small grains are conducive in hot areas; their drought-tolerant nature enables them to thrive in marginal areas making them an appropriate strategy in responding to climate change. However, several production and policy challenges associated with small grain production hinder their adoption by farmers. In view of this, this chapter discusses the potential of small grains as an adaptation strategy to climate change in Zvishavane District, Zimbabwe, and addresses potential challenges and opportunities for increased adoption and future research. The review showed that farmers in Zvishavane have perceived climate change due to noticeable changes in rainfall and temperature patterns in the past years. Despite small grain production being the best strategy due to drought and high temperature tolerance, an insignificant number of Zvishavane farmers is involved in small grain production. This is due to numerous barriers such as high labor demand associated with small grain production, the challenge posed by the quelea birds, food preferences, low markets, and low extension services and government support. It is therefore necessary to encourage adoption of small grains by developing improved varieties, adoption of climate smart agricultural practices, improved technical support, and access to markets among other interventions.

In microforming scaling down the size of the process while the grain size is kept relatively constant usually results in inhomogeneous deformation. In most works, the inhomogeneous deformation of miniaturized samples is presented and evaluated by microstructure analyses of the deformed grains. However, in certain microforming processes, such as microextrusion, where the final texture of the conventional macro size samples is well known, texture analyses can provide useful information about the deformation.

Resumen
As the final machining procedure of precision components, lapping is often regarded as an important step affecting surface quality, machining accuracy and machining efficiency. Due to some drawbacks of free-abrasive lapping such as deep scratches on the lapped surface, lower lapping efficiency for lower lapping speed, severe waste of abrasive, high processing cost, and so on, fixed-abrasive lapping technology was put forward and developed recently. Meanwhile, considering the unique advantages of the ultrasonic vibration aided machining in the processing of hard-brittle materials such as engine

Resumen
Like other crop improvement programs, a key prerequisite for the CGIAR Research Program on Grain Legumes and Dryland Cereals (CRP GLDC) to generate large-scale impact is large-scale adoption. Hence, evidencing the breadth and depth of such adoption is both of intrinsic interest and important for estimating downstream impacts, such as improved food and nutritional security, income, resilience, and soil health. While various GLDC adoption studies have been undertaken, a recent effort to systematically review these studies and synthesize the results is lacking. We undertook such a review, identif

Resumen
The underlying similarity between soils, grains, fertilizers, concentrated animal feed, pellets, and mixtures is that they are all granular materials used in agriculture. Modeling such materials is a complex process due to the spatial variability of such media, the origin of the material (natural or biological), the nonlinearity of these materials, the contact phenomenon and flow that occur at the interface zone and between these granular materials, as well as the dynamic effect of the interaction process. The lack of a tool for studying such materials has limited the understanding of the phen

Resumen
A researcher at the University of Aberdeen has found that almost 20% (n=70) of secondary schools in Scotland specify an exclusive supplier for school uniform. The research shows that almost every secondary school has a compulsory uniform (over 96%). Of the 343 schools with a compulsory uniform, 320 uniforms include a school tie, 235 include a blazer and 200 schools ban jeans. While the Scottish Government has called for the automatic payment of benefits such as the national minimum clothing grant , only 6 local authorities make automatic awards of this grant when families are applying for othe

Resumen
This study explores the presence of gender bias in public grants for science and technology (S&amp;T) activities known as the Matilda effect in STEM disciplines (science, technology, engineering, and mathematics) in Argentina. The empirical analysis is based on the Scientific and Technological Research Projects program (PICT in Spanish) for the period 20032015 and found that female researchers are less likely to be awarded the first time they apply for a research grant than their male counterparts (-6.2 percentage points, or p.p.).

Resumen
Community contributions are often required as part of community-driven development (CDD) programmes, with payment encouraged through matching grants. However, little remains known about the impact of matching grants, or the implications of requiring community contributions in order for communities to receive development funding. This paper describes research where we partner with two non-governmental organisations (NGOs) – one international and one Somali – and undertake a randomised control trial of a CDD matching grant programme designed to incentivise informal contributions for local public

Resumen
Sliding friction on ice and snow is characteristically low at temperatures common on Earth’s surface. This slipperiness underlies efficient sleds, winter sports, and the need for specialized tires. Friction can also play micro-mechanical role affecting ice compressive and crushing strengths. Researchers have proposed several mechanisms thought to govern ice and snow friction, but directly validating the underlying mechanics has been difficult. This may be changing, as instruments capable of micro-scale measurements and imaging are now being brought to bear on friction studies. Nevertheless, gi
